I don't see how Nancy's comment implies the existence of known or set goals and strategies. Even without knowing what societies goals will be in the future, there are certainly instrumental values that will probably be highly valued (general honesty, restraint from casual physical violence, etc.). Likewise, without knowing what specifically my children will value, I can teach them some basic skills that will likely be useful for getting what they value (and of course, teaching instrumental skills also increases the likelihood that the child will grow to value things that utilize those skills anyway).
